' Be itknown that I, JOHN A. J ossELYN, of the town of Brookfield,county of Worcester, and Commonwealth'of Massachusetts, have in-l ventedcertain new and useful Improvements in Scrap-Leather-Splitting Machines;and I do hereby declare thefollowing to bea full, clear, Vand exactdescription of the saine, reference being had to't-heaccompanyingdrawings' andletters of reference marked thereon, formingapart of thisspeeilication, and in which- Figure 1 represents so much "of ascrapleather -splitting machine with my irnp'roveh ments applied theretoas is necessary to illustrate my said invention. Fig. 2 represents asection ou line a a, Fig. 1, looking in the direction indicated by thearrow, same figure; and Fig. 3 represents a section indicated by line b,Fig. 1, the feeding-rolls not being shown. 2O v To enable those skilledin the art to which my invention `belongs to make and use the same, Iwill proceed to describe the invention more in detail. y Y

In the drawings, A is the bed; B, the splitting-knife; C, the edgingknife; D, the leatheropener; E, theknife support; F F, the verti-A caltiuLedfeed-TOHS; G G, burr feed-rolls; but as all of these parts are 2fully shown and de i scribed in Letters Patent granted to Ine April 13,1886, a further detailed description is un-v necessary in the presentspecification.

In a scrap leather -splitting machine'it is necessary to have aseam-guide, H, to extend at least from the edging-knife C beyond theaction of the second pair, J J', of scrap-leather feed-rolls I l J J.The feed-rolls I I and J J are supported in suitable bearings, the con-kstruction o'f which is well known and common in this class ofLmachinery, as illustrated in the lpatents to George L. Tyler, March 5,A1881, No. 242,079, February `7, 1882, No. 253,449, and June 2, 1885, No.319,357. \A further description ofthe saune is therefore unnecessary inthis specication, and only sectionsof the journals K K and L Lfof thefeed-Wheels I I' and J Jv are shown. The journal 'K of the feed-roll Idoes not extend beyond the outer end of the feed-rolls, or the end ofthe feed-roll next to the seam-guide H.

A pieceof scrap-leather, M, is shown passing between the feed-rolls I IJ J to be split edge O being cutoff. (See Fig. 1.) p

-`lt is desirable to have `the scrap vpieces pushed `both 'of `whichsets areeprovided with longi- -back of this line or point.

tudinal ilutes or grooves cand feeding ridges or surfaces d. Both thegrooves c and .feedingsurfaces d of each feed-roll are formed diagonallyor out of line with the axis of the roll, lso

that when the end d of any given ridge kkor feedh ing-surfaced next tothe seam-guide is passing 7o,

any given point'in lineA with the axis of the feed-roll its other end,d2, will be in Arear or In Fig.'1 the diagonal grooves c and diagoi nalfeeding ridges or surfaces d are shown,and

to work in harmony-with their'respec'tive up-l y perfeed-rollsthatis,the ends d of the diagonal ridges or feeding-surfaceswill always kbeo in advance off' theirsopposite ends, dz--and as theunder-feed-rolls, 1 andJ, turn np and to the left when actingv upon thescrap ofleather, M, to be split, they have to be 'made with re-Y versediagonal grooves or flutes c and reverse diagonal ridges orfeeding-surfaces d.. to those in .the upper feedrolls, I and J, whichturn down andto the left, asindicated by arrows,v Fig.2, looking in thedirection indicated 'by I prefer to inake the feed-rolls inshell'i'orniand` then spline thenu to-their Vrespective j ournals,since they can bemade more expeditiously inthisway.-

. y In brief, the ends d of the diagonal ridges or corne in contact withthe surface of the scrapleather M; and the remainingy portions of j pthe same diagonal ridges orfeeding-surfaces .1

gradually comein contact with the .piece of ,rOo- Y scrap-leather, whichis thps pfed along by they combined screw action of the dia'gonalrdges Ylit will be understood that the bottonui'eed` Y rolls, I and J, are`ilu'ted or grooved diagonally or feedingsurfaces el on both the upperand lower feed-roll, the action being such as vto force the edge of thepiece of leather up against the seam-guide H, while at the same time thewhole piece is fed along evenly and in av uniform manner to thesplitting-knife, notwithstanding the pieces may vary greatly inthickness.

If preferred in any case, the machine may be arranged so as to dispensewith one set of feed-rolls, in which case the edging-knife, single setof feed-rolls, and splitting-knife would have to be relatively arrangedto operate in harmony; but I prefer to use two sets, as herein shown anddescribed.

' It will be further understood thatin operating upon pieces ofscrap-leather which have one even or straightedge theedging-knife andfirst set of feed-rolls may be dispensed with.

Having described myimprovement in scrapleather-splitting machines,what Iclaim as my invention, and desire to secure by Letters Patent, is-

l l. The combination, with the seam-guide H and edging-knife C, of thefeedrolls I I', provided with diagonal grooves or flutes c and diagonalridges or feeding surfaces d, as described, whereby the ends d next tothe seamgnide of the diagonal feeding ridges or surfaces dare always inadvance of the opposite ends,d2, substantially as and for the purposesset forth.

2. lThe combination, with the seam-guide H and splitting-knife B,of thefeed-rolls J J,pro vided with diagonal groovesor flutes c and diagonalridges or feedi ng-surfaces d, as described, whereby the ends d next tothe seamguideof the diagonal feedingridges or surfaces d are always inadvance of the opposite endsz, substantially as and for the purposes setforth.

3. The combination, with the seam-guide H, edging-knife C, andsplitting-knife B, ofthe two sets of feed-rolls I I and J J, providedwith diagonal grooves or flutes e and diagonal ridges orfeeding-surfaces d, as described, whereby the ends d next to theseam-guide of the diagonal feeding ridges or surfaces d are always inadvance ofthe opposite ends, d2, substantially as and for the purposesset forth.
